Two VERY different men, Meriwether Lewis and William Clark, joined to J, ~ake the first recorded set of scientific observations and measurements of geomorphology and hydrology west of the Mississippi River. They did not limit themselves to these two scientific topics but were true naturalists, making observations and measurements related to astronomy (Large, 1979; Bedini, 1984; Plamondon, 1991; Bergantino, 1998), biology (Cutright, 1969), ecology, ethnology (Ronda, 1984a), geology (Bluemle, 2001; Bergantino, 1998), and phenology, as well as to the general geographical understanding of the arrangements of rivers and other topographical features of the trans-Mississippi West (Allen, 1975) .
